IGNITION TIMING CONTROL Sept. 18, 1951 2 Sheets-Sheet 2 Filed Sept. 30, 1948 3 Inventor George I. Bur/riewicz provided, as indicated in Figure 3, and one end of the enlarged portion 32 of the housing will be provided with a screw-in plug member 43, while the other end of the housing portion 32 will be provided with a recess 44 and the drive shaft 40 will be provided with a diametrically disposed bore 46, whereby the drive pinion 38 may be alternatively secured to the drive shaft 40 on either side of the mitre gear 36, thus allow* ing rotation of the drive shaft 40 in one direction to give alternative directional rotation to the countershaft 34, the arrangement of the drive mitre gear 38 being a matter of preference on the part of the operator of the device.

The drive shaft 40 is provided with a universal joint 48 connecting it with a drive shaft extension 50. The drive shaft extension 50 is journaled within a handle extension 52 which has an ofiset portion pivotedon the end of the steering handle 54 normally provided in outboard motor assemblies by means of a pivotal connec; tion indicated at 56, to allow' movement of the handle extensionBZ in one plane relative 'to the steering handle 54. A-preferred embodiment of this invention includes a thimble 58 which is rigidly pinned, as at 60, on the outer end of the drive shaft extension 50, and which is provided with a resilient hand grip 62.

It is preferred that the different parts of this invention shall be enclosed as fully as possible to guard against interference with the person or clothing of the operator and with this in mind, the crank case I! will be laterally apertured, as indicated at 64 in Figure 6, the housing 28 and contiguous portions being enclosed within the apertured crank case shroud by a crank case patch 66 bolted, as at 68 to cover the aperture 64.

The operation of this invention will be clearly understood upon a consideration of the foregoing description of the mechanical details thereof, taken in connection with the drawings and with the above recitation of the objects of this invention. It will be clear that all of these above objects are amply achieved by this invention.

Obviously variation from the embodiment of this invention set forth in the drawings and specification may be resorted to without departure from the spirit of this invention, the configuration of the hand grip, housing and means of attachment of the device on a motor being dictated in part by the type of motor wherewith this invention is to be used.

Accordingly, this invention should be limited only in accordance with a proper interpretation of the terms used in the sub-joined claims.

Having described the invention, claimed as new is:

1. In an outboard motor having a casing and mechanically interconnected throttle control means and ignition timing control means, a steering handle on said motor, an ignition timing stator plate, a sector gear on the stator plate, a housing fixed exteriorly on said casing, a sector pinion engaging said sector gear, a countershaft rotatively mounted in said housing carrying said what is sector pinion at one end of the countershaft, a mitre gear secured to the other end of said countershaft, a drive shaft rotatably mounted on said steeringhandle of said motor and journaled on said housing and having a drive mitre gear engaging the mitre gear on the countershaft, whereby both throttle and ignition settings may be controlled by manually rotating said drive shaft.

- 2.7 In an outboard motor having a casing and mechanically interconnected throttle control means and ignition timing control means, a steer-. ing handle-0n said motor, an ignition timing stator plate, a sector gear on the stator plate, a housing fixed exteriorly on said casing, a sector pinion engaging said sector gear, a countershaft rotatively mounted in said housing carrying said sector pinion at one end of the countershaft, a mitre gear secured to the other end of said countershaft, a drive shaft rotatably mounted on said steering handle of said motor and journaled on said housing and having a drive mitre gear engaging the mitre gear on the countershaft, whereby both throttle and ignition settings may be controlled by manually rotating said drive shaft, a handle extension having a hand grip connected to said handle by a joint allowing movement in one plane relative to said handle, and a drive shaft extension carried by said handle extension andoperatively connected to said hand grip and connected by a universal joint to said drive shaft.

- GEORGE F. IBU'I'KIEWICZ.
